this should fix it. You need to set Str before using it in the query.
str = ListBox1.SelectedItem.ToString<br />
Dim cmd1 As New OleDbCommand("select id from table3 where news1 ='" & str & "' ", con)<br />
Dim dr As OleDbDataReader<br />

Hi,

Why do you want to do that? Showing/hiding of control is client side functionality. You can not access the state from the server.
You can save the state on hidden field and pass it to the server though!

Why don´t you use <asp:panel> instead of <div>?
The Panel control generate the same code ( <div></div> ) and can be manipulated in code behind.

Guys,
I'm developed a quiet complex searh page for my company and produced the results in a datagrid.
I'm following N-Tier structure so I have a view model (SortSearch.aspx), Business Logic (SortSearchManagement.vb) and Data Access Layer (SortsearchDA.vb).
I created ObjectDataSource that is getting list of objects (SearchResultEntity) and the searching conditions are stored in a session as well as sortingexpression, sorting direction and others as it shows below
<asp:ObjectDataSource ID="SearchResultsObjectDataSource" runat="server"
SelectMethod="getRequests" TypeName="ATVS.Initiation.BLL.SortSearchManager"
SortParameterName="SortExpression">
<SelectParameters>
<asp:SessionParameter Name="searchCriteria" SessionField="SearchCriteria"
Type="Object" />
<asp:SessionParameter DefaultValue="" Name="SearchType" SessionField="TYPE"
Type="String" />
<asp:SessionParameter Name="UserGroup" SessionField="USERGROUP" Type="Int32" />
<asp:SessionParameter Name="SortExpression" SessionField="SortExpression"
Type="String" />
<asp:SessionParameter Name="SortDirection" SessionField="SortDirestion"
Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>
The grid contains multiple columns and some of its columns contains buttons and hyperlink as shown below:
<asp:GridView ID="resultsGrid" runat="server" AllowPaging="True"
AutoGenerateColumns="False"

AllowSorting="True">

I turned autosorting on and wrote a cutomized sorting event as shown below
Protected Sub resultsGrid_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles resultsGrid.Sorting
Session("SortDirestion") = CInt(e.SortDirection)
Session("SortExpression") = e.SortExpression.ToString()
resultsGrid.DataBind()
End Sub
I have two issues:
1. The session value SortExpression is passing nothing to Data Access Layer? While it is passing all others?
2. Once I click on a column header every thing went well but once the grid is rendering it disappears?!!
Here is the Page load event for the aspx file
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsNothing(Session("USERGROUP")) Then
Response.Redirect("Default.aspx")
End If
Session("TYPE") = Request.QueryString("TYPE")
resultsGrid.Visible = False
If Session("TYPE") = "" Then
Session("TYPE") = "ALL"
End If
Dim type As String = Session("TYPE")
If type.Equals("FOLLOWUP") Or type.Equals("OVERRIDE") Then
statusDropDownList.Visible = False
StatusLabel.Visible = False
End If
If Not IsPostBack Then
Session("SortDirestion") = 0
Session("SortExpression") = "ARID"
End If
End Sub
Here are all events for GridView control
Protected Sub resultsGrid_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles resultsGrid.PageIndexChanging

Hello ,everybody, I'm a chinese,and my english is so bad.
I'm the beginner in VS2008.
I have a question about the masterpage.
When I build a new masterpage,a question appear.
The source code like this:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage2.master.cs" Inherits="MasterPage2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
I don't do any change in the source code.
But the design view give me mistake like this:
//-----------------
Error Rendering Control - ContentPlaceHolder1
An unhandled exception has occurred.
This control can only be used in a MasterPage.
//-----------------
|
|
|
|
|
The above code does not give any error when I put your code in a master page in VS 2008.
Please check your extension of the above master page.
The above error could occure if you put the above code in an .aspx file.
Master pages should have the extension of .master.
|
|
|
|
|
Thank you.
But ,I checked my file's name,it is sure that the master page have the extension of .master.
Besides,I do a further checking.
When I remove the blank line in the "div" tags,the design view run normal.
Then I restored the blank line ,the page also gone well.
Next,I rebuild a master page again,the same as the last,design view report the mistake.
Then I remove the code <asp:ContentPlaceHolder id="head" runat="server"> </asp:ContentPlaceHolder> in the "head" tags,the master page also could run normal without mistake.
Like the last step,I restored the code in "head" tags,the master page run well.
I think,is there any bug with the VS2008 in my computer?
Because I also meet a similar problem about the master page in another project. The mster page run very well,but the other .aspx pages which use the master page,have nothing in design view.
All the above-mentioned pages can run very well in Browser.
And the Wrong master pages also can view normally with no mistakes in VS2005.

It looks like a hardware problem, are you sure that hard ware is correct?
be a part of the solution, rather then problem
|
|
|
|
|
Yes Hardware Is ok.
Even i am run application using real ip address from my pC.it's Work fine But If Some One Access Application From Remote PC.The Port Number disable Permanently. Now if i Restart my Machine All Works Fine Again.
So i not think this Hardware Problem they may be security problem but not exact know.
Thanks for answer.

Hi Guys,
I need your help I have forms authentication setup on an asp.net portal. Even though I have the auth ticket to "NOT" persist, it does so after closing the browser... I have tried all the tricks with FormsAuthentication.SignOut() but still no cure.
Is there a way I could get rid of the forms auth cookie when the client browser is closed??
Many thanks in advance
Green Grape

How? That's the first thing I would check. If there is a mechanism that is supposed to result in the browser not caching the cookie and it's not working then the first thing I would suspect is my implementation of the mechanism.

Mike, I don't know what's causing it to behaive this way... I'm running out of options!
This is my code:
if (_IsAuthenticated)
{
FormsAuthenticationTicket _ticket = new FormsAuthenticationTicket(1,
this.userHandletbx.Text + "_" + DateTime.Now.ToString(),
DateTime.Now,
DateTime.Now.AddMinutes(30),
false,
String.Empty,
FormsAuthentication.FormsCookiePath);
string _encryptedTicket = FormsAuthentication.Encrypt(_ticket);
HttpCookie _authCookie = new HttpCookie(
FormsAuthentication.FormsCookieName,
_encryptedTicket);
_authCookie.Secure = false;
Response.Cookies.Add(_authCookie);
FormsAuthentication.RedirectFromLoginPage(this.userHandletbx.Text, true);
}
And this is my web.config:
<authentication mode="Forms">
<forms loginUrl="Login.aspx"
name=".ASPXFORMSAUTH"
protection="All"
path="/"
timeout="40"
defaultUrl="Home.aspx"
enableCrossAppRedirects="false"
slidingExpiration="true">
</forms>
</authentication>
...and no matter where I stick
FormsAuthentication.SignOut() it doesn't kill that darn cookie!
Am I missing something? Is this a blonde moment I'm having? 
Thanks for your help, by the way.

First two obvious questions are:
1) Is the code executing? The function can't work if it is never being called.
2) Have you followed all the directions of the documentation for the SignOut method?
